So I'm a long time Blackberry user who got a US Iphone 3G from a friend who upgraded to an Iphone 4. I have T-mobile so I'm working on jailbreaking+unlocking it and after spedning hours online finding the most confusing info ever, I found this forum and was saved (almost LOL), woo hooo. I spent another hour or so reading previous posts and I cannot quite find my specific case (please correct me if I'm wrong, this forum is BIG), so here it goes: I jailbroke it with Redsn0w and everything went pretty smooth. My next step would have been to unlock it (to use my t-mobile sim in it) using ultrasn0w through Cydia BUT the icon for it is simply a shaded white square and when I start the Cydia app it starts by saying "loading data" on a black background for a second or two, then it goes into a "normal" app background where it says "Error: Refreshing Data Method http has died unexpectedly! Sub-process http received signal 5." and a button that says "okay" underneath that... After that I get a "unable to load (request timed out). So i went to check if my home's wireless connection that I am using to feed data to the iphone is working and to my amazement, safari worked fine for the first link I tried from my favourites the iphone got form my laptop (an Italian motorcycle forum) but anything else I try, including google.com, yahoo.com time out and I get Cannot Open Page Safari could not open the page because the server stopped responding... As of right now I am sitting in the corner of the room with the Iphone in my hand slowly rocking back and forth while mumbling incoherent phrases... LOL Please help!!
