Nokia 7710 Prototype F4.0: Future ahead of its Time | Unreleased Black Keypad
Quick ViewA rare and impeccably preserved Nokia 7710 RM-12 F4.0 prototype, belonging to the final stage of Nokia’s pre-production cycle for the iconic Series 90 touchscreen smartphone. This F4.0 unit – clearly marked PROTO and Property of Nokia – originates from Nokia’s internal validation program, used during the last wave of field testing, UI refinement and RF certification before the public release in 2005.
Unlike retail units, this prototype features an unreleased keypad colour variant, with silver-toned navigation and side-control keys replacing the standard glossy black retail trim. This experimental colourway never reached commercial production, making this device a standout among surviving prototypes. The front bezel also shows the slightly grainier, matte finish characteristic of late hardware trials inside Nokia’s labs.
As with all authentic high-grade prototypes, the label carries the signature “Model: XXXX” placeholder, missing consumer certifications, serial markings and final manufacturing codes. These elements confirm it as a genuine internal unit, built in Finland during the last engineering revision of the platform.
The Nokia 7710 was Nokia’s most ambitious early touchscreen smartphone – a widescreen 640×320 device running the innovative Series 90 interface on Symbian OS. The prototype here predates the public release, offering collectors a rare glimpse into Nokia’s transition from experimental UI concepts to finalized commercial design.
This F4.0 RM-12 prototype is an exceptional find: a fully authentic late-stage engineering device with a unique, unreleased keypad trim, placing it among the rarest surviving 7710 variants and a valuable centrepiece for any advanced vintage Nokia collection.

Nokia C5-02 Prototype | China Telecom CDMA Engineering Unit
Quick ViewA never-released Nokia C5-02 engineering prototype, built for China Telecom’s CDMA network. Under the battery, the label still reads “Property of Nokia, Not for sale” (Type RM-686, HWID 2000, made in China).
A slider that mixes a touchscreen and stylus with a full numeric keypad, Chinese input keys and the China Telecom eSurfing swirl on the navigation key, plus a 5-megapixel camera. CDMA prototypes from Nokia’s China programme rarely surface outside China.
The phone is functional. The only weak point is the screen, which is not in its best shape: the display looks faded. It comes with its stylus and a Nokia BL-5F battery.

Nokia N91 8GB Prototype B4.0: Made in USA | Unreleased white white Camera Cover and silver keypad
Quick ViewNokia N91 8GB – RM-43 – Prototype B4.0 – Made in USA – Unique White Camera Cover
This is a highly significant Nokia N91 8GB engineering prototype, built during Nokia’s internal development cycle and never intended for commercial release. The label identifies it as PROTO B4.0, a late-stage pre-production unit, but the hardware reveals something even more remarkable: a white camera cover, a part that was never used in production N91 or N91 8GB units.
All retail models featured a dark grey/black camera bezel, but this prototype houses a white pre-final CMF component – a rare internal test part used before Nokia approved the final color and material selection. Early tooling marks, alternate finishing, and non-standard coloration make this one of the only known N91 prototypes with this configuration.
Unlike mass-produced units manufactured in Finland or Germany, this device also carries the exceptionally rare “Made in USA” marking, confirming its role as a high-level engineering sample assembled for internal testing and hardware validation. The model field reads “XXXX”, and multiple internal codes differ from final production, reinforcing its early-preproduction status.
As the world’s first smartphone with an integrated 8GB micro-hard-drive, the N91 was born from bold experimentation – and this prototype embodies exactly that phase of innovation. With its unique white camera cover, U.S.-assembled chassis, RM-43 pre-production hardware, and B4.0 revision status, this unit stands as a near-one-of-a-kind artifact from Nokia’s golden age.

Nokia N92 Prototype S3.4 | An Unreleased Black & Grey Design
Quick ViewNokia N92 S3.4 Prototype – The Elusive Black & Grey Variant
In 2005, Nokia was pursuing an ambitious vision: transforming the mobile phone into a portable television. The Nokia N92 became one of the most unconventional devices of the Nseries era, introducing integrated DVB-H television reception, a remarkable dual-hinge rotating display and a multimedia experience designed years before mobile video streaming became part of everyday life.
This particular unit is an exceptionally interesting S3.4 pre-production prototype, distinguished by its striking black and grey colour combination. Unlike the familiar commercial N92, this prototype presents an alternative visual identity, offering a fascinating glimpse into Nokia’s experimental design and development process.
But the differences go far beyond its unusual colour scheme. One of the most intriguing details is the noticeably larger memory card cover, a physical design variation that distinguishes this early unit from the final production model. Even more interesting is the clamshell closing mechanism, which differs from the commercial N92 when the device is folded shut. These subtle but significant differences reveal that Nokia was experimenting not only with colours and finishes, but also with the mechanical construction and physical design of the device.
The S3.4 development designation adds another layer of intrigue. This is not simply a standard N92 dressed in an unusual housing, but a pre-production specimen displaying tangible differences from the retail hardware. The combination of its distinctive finish, modified memory card cover and alternative clamshell closing arrangement makes it a particularly compelling example of Nokia’s engineering evolution.
What makes the N92 especially fascinating is the extraordinary ambition behind its design. Its rotating display could transform the device from a conventional mobile phone into a miniature widescreen television, while DVB-H technology represented Nokia’s vision of a future where television could be enjoyed almost anywhere.
For serious Nokia collectors, surviving prototypes with visible structural differences are particularly significant. They preserve evidence of design decisions, mechanical experiments and engineering refinements that may have disappeared entirely before commercial production. This black and grey S3.4 prototype offers precisely that: a rare opportunity to examine an alternative stage in the development of one of Nokia’s most unconventional devices.
More than an unusual colour variation, this is a different interpretation of the Nokia N92 itself – a remarkable survivor from a time when Nokia was still experimenting with how the future of mobile technology should look, feel and function.

Nokia Unknown Model Prototype: CodeName Kabaka | Unreleased
Quick ViewNokia NPM-3NA “Caballa” – Unreleased 3G Prototype (2001)
The Nokia NPM-3NA is an extremely rare, unreleased prototype developed around 2001 during Nokia’s early work on Japan’s first 3G network, NTT DoCoMo’s FOMA. Built in very small internal batches, this device was used for radio testing, firmware evaluation and UI experiments, and was never certified or intended for public sale.
Running prototype firmware V55.40 (31-10-01) with the internal ? NMP signature and showing an unassigned IMEI (??????????????), the phone carries all hallmarks of an engineering sample. The internal hardware label NE8_06 / HW0250 suggests a development board related to NEC, a major DoCoMo technology partner in the early W-CDMA era. Its long extendable antenna and unique keypad design match the style of early FOMA trial devices, such as NEC’s X2001V.
With no public documentation, no final RM code, and no retail equivalent, the NPM-3NA stands as a rare glimpse into Nokia’s abandoned Japanese-market 3G program. A genuine collector-grade prototype, extremely uncommon and historically significant for anyone interested in unreleased Nokia hardware or the origins of modern 3G technology.
