Hello! I haven't posted a thread here in forever, but I do need some MacRumors help now. First off, I already searched the first page of this forum and mroogled "iphone 3g only using edge data". Basically, my problem is that my iPhone 3GS is only using Edge data (an E in the top left corner, and noticeably slower internet speeds). I'll restate everything that happened around the time when it stopped working in case it'll help. Yesterday, I went with my family to go to the beach in Canada (we live in the United States). I brought my iPhone (black, 32 GB, bought in early July) with me as usual. I don't often use headphones, but I brought the included headphones with me so I could listen to my iPod during the car ride and on the beach. I put my headphones in, put on some Sufjan Stevens, and expected everything to go fine. Instead, the sound came out the speaker. Thinking it was a simple problem, I blew some air into the headphone jack, tried my sisters headphones, and still couldn't get the iPhone to output sound through the headphones. I did a quick Google search and decided to reset the settings of my iPhone. I did that, and the headphones worked. Fine. Later, while almost at the border (no more than 10 minutes from my house, definitely not enough to go out of a coverage zone), I wanted to check Facebook and noticed I was using Edge data. I thought this was weird, but forgot about it when I turned off data due to the fact that I was "switched over" to Rogers Wireless in Canada. However, even after we came home, the Edge data never went away. This is a full day later, and there are still no signs of 3G data coming my way. Any help is greatly appreciated. I have an Apple Store not too far from my house, and it wouldn't be a hassle to go there soon. But I use 3G on my phone a lot, and this is relatively irritating. So, any "at home" remedies will be very helpful. Thanks!
