  • Nokia 6788i: The Ultra-Rare China Mobile Metal Slider

    💎 Rarity Index: S (Ultra Rare)

    ⭐ WOW Factor: One of the very few Nokia phones ever built exclusively for China’s TD-SCDMA network – effectively locked to a single country and produced in extremely limited quantities.

    👁 Evaluation in my collection: BNIB – 10/10

    🕵 Nokia Codename: Harbin

    ⏱ Life timer: 0m | 📦 Boxed: YES

    📅 Release Year: 2010 | 💰 Release Price: ~90 €

    📊 Units Sold: ~200k


    📰 Why this phone matters: The Nokia 6788i (RM-636) is a China-only smartphone released in 2010, designed specifically for China Mobile’s TD-SCDMA/GSM dual-mode network. Constructed around a solid metal frame with metallic accent panels, the 6788i features a premium sliding mechanism and rugged build quality rarely found in region-exclusive Nokia devices.

    This model was created during Nokia’s short-lived TD-SCDMA development phase, and because the technology existed only in China, the 6788i never reached the eur;opean or international market. Production volumes were extremely limited, and nearly all units stayed within China Mobile’s distribution channels – making surviving examples extremely rare for collectors worldwide.

    The phone runs a China-specific firmware package and represents a unique combination of Nokia industrial design, metal-slider craftsmanship, and a specialized 3G technology Nokia used only once.

    This particular unit is BNIB (Brand New In Box) – an exceptionally difficult condition to find for any China-exclusive Nokia, elevating it to true museum-grade status within any serious Nokia collection.

  • Nokia 8208: Dual-Slider Elite. The Rarest CDMA Flagship Nokia Ever Built

    💎 Rarity Index: S (Ultra Rare)

    ⭐ WOW Factor: Rare Nokia Dual-Slider CDMA Flagship (China-Exclusive, Short Production Run)

    👁 Evaluation in my collection: BNIB – 10/10

    ⏱ Life timer: 0 | 📦 Boxed: YES

    📅 Release Year: 2009 | 💰 Release Price: 300 €

    📊 Units Sold: ~200k


    📰 Why this phone matters: The Nokia 8208 stands out as one of Nokia’s most distinctive high-end CDMA phones, created exclusively for the Chinese market in 2009. Built for China Telecom’s premium segment, it delivers a rare combination of power, design originality, and luxury-grade construction that places it among the most collectible CDMA-era Nokias ever made. This unit is preserved in factory-new condition, an exceptional find considering how few 8208 units escaped heavy carrier use. BNIB status significantly elevates its desirability and rarity for collectors.

    Its signature feature is the dual-slider design: slide up to reveal the keypad, slide down for dedicated multimedia controls – a layout rarely seen on a Nokia device. Combined with its solid feel, metal structural elements, sharp lines, and balanced weight, the 8208 feels like a deliberately crafted premium instrument rather than a typical feature phone.

    Production numbers were limited, and the model never officially reached markets outside China, making surviving units scarce worldwide – especially in top condition.

  • Nokia N78

    💎 Rarity Index: C (Common)

    ⭐ WOW Factor: The first Nokia phone with the new extended guitar-based version of the Nokia Tune

    👁 Evaluation in my collection: Great – 9.5/10

    ⏱ Life timer: 130h | 📦 Boxed: NO

    📅 Release Year: 2008 | 💰 Release Price: ~350 €

    📊 Units Sold: ~2M


    📰 Why this phone matters: The Nokia N78 is a 3G smartphone made by Nokia. It was first introduced at the Mobile World Congress on 11 February 2008, and was launched on 26 May 2008 for &eur;o;350 before taxes and subsidies. It runs on Symbian 9.3 (S60 3rd Edition, FP2) and was marketed as a more cheaper Nseries device inside a compact, light body. The phone is compatible with the N-Gage 2.0 mobile gaming service.

    It is the successor of the N73 and its design shares similarities with the N81, N82 and N96. Despite its relatively low price, the Nokia N78 does still pack numerous standard Nseries features such as A-GPS, HSDPA and Wi-Fi. It has a touch-sensitive Navi wheel like on the N81, and was the first Nokia (and among the first overall, along with Sony Ericsson W980) to feature an FM transmitter. Its keypad is hidden in idle mode and lights up when a key is pressed. It did not however become popular like the N73 was. Later in 2008 the Nokia N79 was introduced.

    The Nokia N78 was also the first Nokia phone with the new extended guitar-based version of the Nokia Tune.
