Guest eccramer Posted May 25, 2008 Report Share Posted May 25, 2008 Please excuse my newbness, but I am in need of the wise minds of MoDaCo. I did some searching, and found some answers, but I wanted to check before I actually bite the bullet and upgrade, in the event that I'm misinformed and screw up my phone. I have an unlocked Tmobile Dash that I use on AT&T. I quite like it, but have been experiencing some stability issues and would like to upgrade to WinMob 6. I have the official installer from the wmupgrade page on Tmobile, but I'm curious whether or not upgrading will SIM lock my phone to tmobile again. While I did search (and found the afore-linked thread) it gave some conflicting information. I understand the difference between SIM and CID unlocking, but It's still not clear to me that my phone will still be SIM unlocked after I upgrade with the official TMobile install application. Two people in the thread I found say yes, and two say no. So, can anyone shed some light on the issue? Thank you in advance. Link to comment Share on other sites More sharing options...

No your phone will not be sim-locked after you flash if its sim-unlocked before you flash. Go for it :D Link to comment Share on other sites More sharing options...
Guest whos-rog Posted May 29, 2008 Report Share Posted May 29, 2008 Go for it i went from 5-6.1 last night, works perfect again i have a sim unlocked device and it did not effect it or revert it back. I used the xda-devlopers website. Found it very helpful and contains the roms and instructions. (this is a good site too) Link to comment Share on other sites More sharing options...
