After the debut of the original Motorola DROID, we saw the Motorola Milestone arrive for GSM users. The same followed with the Motorola DROID 2 and Milestone 2 so it comes as no surprise that the Motorola DROID 3 will be coming as the Milestone 3 to AT&T eventually.
AT&T Motorola DROID 3 a.k.a Milestone 3 hits FCC
According to AndroidCommunity, a GSM Motorola Droid 3 (XT682) has hit the FCC with AT&T bands. The blog made the discovery via an FCC filing which showed that the GSM phone supports 850/1900 bands as well as WCDMA bands II and V i.e. AT&T compatible.
Given that the Motorola DROID 3 was released on Verizon Wireless nearly 8 months ago, we can expect the current Motorola DROID 4 to arrive as a Milestone 4 no sooner than the holidays. So until then, this QWERTY phone will be your best bet.
