Could someone please tell me which is the best custom GSM rom and the right kernel for it
If you are looking for GSM, most current ROMs contain all the GSM code needed, a special ROM/Kernel combination is not needed, just install the ROM, go to the Mobile Network settings and change the network type to GSM/WCDMA (or whatever is appropriate in your situation) and add the APNs accordingly. Note that HSPA (and on rare occasions HSPA+) are possible, but it is hit and miss, some people can get good data, others not so much, and some have to go in and do NV edits to get decent data. All this stuff is discussed in detail in the XDA Rezound sections. http://forum.xda-developers.com/forumdisplay.php?f=1389
Note that XDA has a reputation for not being the nicest to newbies, somewhat correct, but if you do your homework and reading first and ask intelligent questions, you will be fine.
