T-Mobile USA 2G / 3G / 3.5G / HSPA+ / "4G"
Anybody on T-Mobile US with the p990 / su660?
I'd like to hear if you are also having problems I have had...I can only have stable signal when choosing "2G only". Otherwise, signal keeps dropping and end up with "No Service".
I realize that to have access to HSPA+, the frequency needed are 1700 / 2100. My su660 has 2100 but not 1700. Does this mean I cannot access the HSPA+ speed?
If not, then what can I do to get at least the 3G speed? that is without service drops. I tried manually entering the APN with the "T-Mobile G2" setting (the one with proxy server address), but still no luck.
Thanks in advance. I'd appreciate any advice you may have!
Found solution here on how to resolve network service drops for my CM9. Huge thanks to TIITHE
, I cannot use 3G/3.5G (marketed as "4G" by T-mobile USA) with my SU660 O2x. Apparently a phone needs to support the 1700 MHz frequency in order to have 3G speeds on the TMO US.

I'm not too familiar with temasek's builds. Are they based on the same code as the CM7.2 RC1? If so, then you don't have to do a full wipe.
In general, full wipe is recommended and needed to be "safe" as you said. But if you're flashing same kinds of roms, it's not necessary. For example, if you regularly flash the cm nightlies, it's not necessary. I also regularly flash Owain's CM9 kangs without full wipe in between.
There were times though I messed up something badly between flashes and did a full wipe.
But as long as you have a good nandroid backup, you should be safe. Feel free to experiment! (I've learned a lot this way)
