Both Carphone Warehouse and Phones4U have stopped selling the aging Google handset, although you can still buy it from Google direct and through networks like O2.
This stock slow-down chucks gasoline onto the fire of speculation that we'll see the Nexus 5 launch at Google I/O in June.
And IO IO IO
Some rumours point to LG again being behind the Nexus 5, having made the sparkly-backed Nexus 4.
Or will simply see a new version of the Nexus 4 - some pre-IO chatter has pegged Google as planning a 32GB version of the handset with LTE on board.
Either way, we're expecting the next Nexus to come rocking a new version of Android, specifically Key Lime Pie (Android 5.0) - although there may be a delay between the big unveil and the OS launch as Google lets manufacturers' hardware catch up with its software.
