We told you earlier this month that the Nexus One would be coming to AT&T and we now have the first sharable shred of evidence that our source was spot on. Spotted emerging from the testing halls of the FCC is an unknown mobile phone with the FCC ID NM899110. For the geeky folk, the NM8 is the FCC Grantee code for HTC while 99110 is the model. People who rock a Nexus One and have a penchant for studying FCC labels would notice that the FCC ID for this mystery handset is only a single digit away from the FCC ID of the current Nexus One (NM899100) and would be quick to recognize that this mystery handset is most likely a kissing cousin to their T-Mobile-friendly handset. Without looking at the FCC documents, one might casually pass this mystery handset off as the upcoming Verizon Wireless CDMA version, but a quick perusal of the testing report reveals that the handset in question is rocking WCDMA bands I, II and V which are decidedly AT&T. Any Nexus One owners crawling on AT&T’s EDGE a bit peeved by this discovery?
