I just got the razr maxx and in addition to my gmail account I have two corporate email accounts set up (1&1 IMAP). Of those two accounts I have one of them set up for push notifications and the other for manual fetch. Gmail notifications work just fine, but the corp account I have set up for push will only receive notifications when I'm on a WiFi network and not on 4G. Tried looking to see if there was something in general settings and the settings within the email app, but couldn't find anything. Anyone have an idea why push isn't working on 4G? Thanks!
