I have an iPhone 3GS, not unlocked or jailbroken. Running on TELUS HSPA (CANADA) network, no issues when I got the phone brand new in January, ever since middle of May I have had issues with having full signal and 3G and having no service! |When I only have the issue when I am in one certain location but I am also jumping on AT&T signal and have to reset the phone. On the phone with my carrier TELUS and they cannot fix the problem. Today I woke up and found the phone on AT&T, then as I went to work it took several hard resets (home button and silent button pressed simultaneously) to get it back to TELUS, it even jumped to T-Mobile. I live in a border town Windsor, Ontario-CANADA across the river from Detroit, Michigan but I am not directly near the river when this occurs, this is not happening to anyone else I know that lives in the city that has an iPhone. Even when I cross the border I have to switch the phone over to AT&T for service, I even swapped out my old original SIM card for a new one and still the same issue. Before I did that I got a new replacement iPhone from Apple, which did not solve the problem, once I had put my SIM card (original) into the new phone and synced the phone with iTunes it had the same issues 20 minutes later when I tried to access the internet. WTF!!
