So... I'm with Verizon (U.S) on 2 of my lines, and need a 3rd and 4th and really wanted to go GSM with those (something different). My question though is which GSM carrier (U.S) plays the nicest (as far as frequencies) with the BlackBerries of overseas and the Porsche editions as far as getting FULL 4G. AT&T or T-Mobile? Thanks for any and all info.

You won't really get LTE on European/rest of the world (ROW) Z10/Q5/Q10/Z30. So by 4G, I'm going to assume you mean HSPA+ :

Z10 STL100-1: 3G/HSPA+ on AT&T everywhere AT&T has 3G/HSPA+. 3G/HSPA+ in some places on TMO.
Z10 STL100-2: 3G/HSPA+ on AT&T in some places.

Q5 SQR100-2, SQR100-3: same as STL100-1

Q10 SQN100-3: same as STL100-1

Z30 STA100-2, STA100-6: same as STL100-1


But if you're also including Canada,

Z10 STL100-3: perfect fit for AT&T and TMO (including LTE)-->best Z10 option for AT&T and/or TMO
Q5 SQR100-1: perfect fit for AT&T and TMO (including LTE)-->best Q5 option for AT&T and/or TMO
Q10 SQN100-1: perfect fit for AT&T, 3G/HSPA+ in some places on TMO, but LTE everywhere
Q10 SQN100-5 same as Z10 STL100-3-->best Q10 option for AT&T and/or TMO
Z30 STA100-5: perfect fit for TMO, 3G/HSPA+ on AT&T everywhere but LTE in some places only-->best Z30 option for TMO, and unfortunately, AT&T also.

So, overall, the overseas models (non-Canadian) have better compatibility with AT&T. I'm too lazy to look up the Porsche phones, but I would guess it's the same pattern.
