for those of you wanting the deb for the new celeste beta which is iOS 5.x compatable, i have uploaded it and included the new gremlin and btstack betas, as far as i know it will only work for existing license holders but maybe someone here without a license might want to test anyway and post their results. there are some other dependencies that you will need to install first, i will list them below, before you install the dependencies go to settings in cydia and set user to developer, you can change it back to user after installation!

Using the latest betas from CocoaNuts repo . . . . seems to be working better than it ever it on 4.x . . . . I bought it back then but wasn't that impressed . . . . this version does jpg and music transfers in both directions to my PC . . . . will test to other handsets soon.
