hey guys. Some of you may have had the insufficient space error in the market. The solution is to NOT delete Amazon market, G talk, and City ID They have dependencies that the market needs. since I'm rooted I just freeze them with titanium backup after i Deodexed back to 605...so they dont appear in my app drawer but the market continues to work. I run vortex rom now but it doesn't matter, any ROM should work fine considering you keep those dependent apk's mentioned.
You'll have to SBF back to 605, then install you're Rom and once you get titanium backup you can freeze the apps from above that you don't need as opposed to uninstalling them.
