so I noticed today that I'm unable to go on the amazon website or update my photos on my skydrive camera roll when I'm using "4g" with 3 to 4 bars, but once I go on WiFi, everything is okay. It would say something about the page is unable to load or the pictures can't be updated. Anyone notice this or can confirm this? Is my Titan a dud or is att blocking these certain things? I can look on emails and most other websites just fine...
