Damn it, I keep forgetting this site screws up my quick replies. Anyway...
demonlordoftheround - I know you said that the Tmobile TP2 couldn't run CDMA but I didn't take that as gospel. The reason being is that looking into the specs between the two versions, it shows the Tmobile one having the same 5 bands as Sprint plus 1 extra. I then looked at the Sprint version seeing that the CDMA bands were duplicates of 2 of the GSM capable bands, realized that the unlocked international GSM bands were probably the non duplicates and the complete unlock required to use the Sprint TP2 was required to allow the 2 CDMA bands to actually run domestic GSM. This makes sense as to why 99% of Sprint reps will say that you CANNOT run domestic GSM. Either way, I THOUGHT that maybe it was a firmware thing that could be changed in the Tmobile TP2 to allow CDMA similarly to how the Sprint TP2 can switch between GSM and CDMA on the 850, 1900 bands.
Lesson learned - the processor dictates that capability! At least I now know why
I was looking forward to the Tmobile version because I read that the FM radio wasn't crippled like it was in the Sprint version but I'm still not 100% on that statement, will do some digging on that.
Next up, clarification on the Sprint TP2 being capable of 3G on Tmobile.
eric12341 - I know you stated that you can get 3G HSPA on Tmobile using the Sprint branded TP2 but the conflicting information I've received from the Tmobile rep is that in order to get HSPA (3G) or HSPA+ (4G), you need BOTH of the 1700 and 2100 bands, not just the 2100 band that the Sprint TP2 has. If you can provide the clarification that would be great and might save me the time of digging on the net but I will be doing that until either someone can clear it up for me, or I clear it up myself.
I will also be trying to figure out what makes the phones capable of HSPA+ but considering the result of the processor dictating GSM vs CDMA, I'm going to guess that the processor also dictates which transceiving technology the phone can handle.
Sorry if I'm sounding like a dumbass but I like to know the reasons behind the answers and exactly how and why things work, or at least to more of a point than just yes or no. No disrespect!! I do appreciate the help and advice, I'd be a lot more lost in my searching with out it
