http://forum.xda-developers.com – My old phone is stolen and I now needs a new phone, I ony want a pure android exprience no custom interfaces, so the best choice right now is the galaxy nexus and it costs good for me now. but I have rumers on the net that says that the next nexus will be on sale before the year ends, and Im really confused do the next nexus will be in a high cost that i wont handle, or it will be in the same prince range as the exicting nexus and the old nexus will be more cheep? can any one clear this things up for me ? thanks in advance (HowTos)
