hey, in the past two days, i've visited a hotel with a few friends and in the day we were leaving i woke up to find bubble liquid soaking my iphone 3gs, i ran to the nearest phone store and he cleaned out my screen and said that my mother board is screwed, which is obvious. I'm afraid he couldv'e switched parts like, an original hardware with a chinese one or something? but everytime i switch it on, it gives me the apple logo (i need to have it connected to electricity) and then it turns on with a connect to itunes background, and slide for emergency call, i thought that it may be that my frimware thing, or ios4 update is gone, but when i slid for an emergency call, the same wallpaper i had came up,? this is really comfusing i know, i just want to know wether it was possible to swetich parts, and how would i know with access just to the Slide to phone call (in all languages)
