HSPA+ on Galaxy Note N7000??

view story

http://androidforums.com – I have the international unlocked Galaxy Note, model N7000, and planning on using it on Straight Talk once I get back in the States... but I'm hearing conflicting information on whether this Galaxy Note model is capable of HSPA+ off the AT&T Straight Talk SIM. Is anyone using the N7000 (Galaxy Note) on Straight Talk with AT&T SIM card (not the T-Mobile one), and getting HSPA+ signal??? (General)
