iPhone 4 Not Really Recognized in iTunes?

[monkeydodo3]

Hey guys so I somehow fixed my iPhone 4's distorted screen by spraying compressed air into the charging port. The colors are normal, but the LCD still sorta flickers, not too bad though! Anyways, when I plug it into my computer, it takes a long time for it to be recognized in iTunes (constantly has the loading circle scrolling next to it in iTunes). Since this phone is sorta restored, when I load up the activation screen where it says 'Slide to set up,' there's a small 'i' button there for information. I click it, but only a blank window pops up, which leads me to think that it's baseband chip is destroyed. Another thing that leads me to think this is that when it boots up, it says 'Searching' at the carrier even though I don't have a SIM card loaded in and if I go through setup, it doesn't ask me to detect/join a Wifi network. Please help. Thanks!
