iPhone 4 MyWi vs. Comcast Cable Speed Test
MyWi is an app that turns your jailbroken iPhone into a hotspot. That's right. A wireless router that any device can connect to. It includes WEP security so you can create a password to keep others off your data plan. This along with 3G Unrestrictor are two of the most compelling reasons to jailbreak. You can get MyWi through RockApp in Cydia. While its expensive for an app at $19.99 this is very cheap if it leads you to buy a wifi only iPad as opposed to a 3G one or if you pay for internet access at places like airports. For a more in depth review. Here I did a speed test comparing download speeds on my iMac using the 3G connection on my iPhone 4 with MyWi and my Comcast cable connection through a Linksys router.
