[Q] possibly lose imei flashing ROMs?

view story

http://forum.xda-developers.com – I have a Telus S3 and I know I/we (S3 users) have to be responsible and backup our imei info in case a flashed ROM wipes that data (supposedly not common but a known issue) I just bought my wife a Telus S2X (t989) off eBay and I'm rooting it for her (and flashing) when it gets in. I've searched these forums and haven't found anything specific about this being an issue on these models so I just wanted to ask if its possible. We have a small process to back it up on the S3 but not even sure if that will work on this phone. Sent from my SGH-I747 using xda app-developers app (HowTos)
