Yep done that loads of times mate. I get the phone on Friday, set it up Saturday. Using wifi at home it was superb, really quick. Did a test against a mate whos got the 4, mine was quicker. Did a test against my g/f's s2 and it was of equal speed. But i could not connect to the internet through Safari, at home, work anywhere. After umpteen calls to Orange i was no better off. Reset all settings, did this, did that no better. Double checked they had set my data connection up, they had apparantly. I got fed up and said i want to send it back and set my old phone back up please which they did. The trusty HTC Wildfire, slow to get internet but it allways worked lol. So switched the phone on said to myself f$£k the iphone and went to browse the internet, guess what, it didnt load. What the f&&k.... Ran Orange agian to ask why this isnt working and spoke to a really helpfull guy who said i will sort it. Three txt msgs later telling me new updates, turn phone off etc and low and behold internet is up and running. Sorry to go on but its been a frikin pain in the ass
