hi guys. need some assistance. i currently have an arc s rooted, BL locked, no roms, currently .42. i had my PC companion updated and it suddenly showed me an update for .69. my question is, if i proceed with the update, will i lose root on my phone? if yes, can i still root my phone once its already on .69? won't i have any issue once the official ICS is out and i update it while im on .69 or .62 will be better? sorry for too many questions. just don't want to brick my phone by doing unnecessary updates. please advise. thanks!
