I've been sitting on my AT&T upgrade for almost a year now (currently iPhone 4, and sick of it). I haven't brought myself to upgrade to either the 8X or 920, and at this point I'm wondering if it's even worth it with a possible new OS (WP Blue?) coming late this year. Just curious if I should wait it out and deal with the iPhone for another 6-8 months until another round of WP flagship phones hit AT&T, or just upgrade now?
