Is there any kind of router I can put my iphone's 3g sim card into and have a wifi area? This would be like the verizon mifi. I would gladly purchase a mifi via AT&T if they offered it but they do not or at least they do not in my area. This way I could tether my iPad. I looked into jailbreaking my iphone but it is version 3.1.3 so jailbreaking looked bleak. Anyone else have a solution? Thanks much.
