I was using it for quite awhile and two things I noticed was after calls sometimes the issue with the 3g would happen and would have to use the airplane mode fix, also out of no where would totally lose data and had to reboot to get it back. Everyones experiences are different though so you would have to try it out. I have jumped ship for the time being until there's an update. I am currently running SS 5.3 with no issues what so ever. Might wanna give it a shot till BD returns =)
I used Google voice with my pine no probs I use with my thunderbolt and its really bad voice quality people on the other end tell me they can't hear me and there is a lot of static
