My phone has been tring to upgrade all day. I Installed a tremendous file on the internal memory the other day and that prevented the upgrade. I semi rooted this phone at one point and then it upgraded and i lost control again. If only my mem was full then. Any how im still here waiting to fix this thing and ive just been working too much to figure it all out. I`m aware all i need to do is erase those giant map bundles i downloaded and poof; it will upgrade; so im standng by and hope that my having noted my experiance on here is useful in some way!? ciao
