For those that have purchased MyWi, Do you have any problems with it? Any issues connecting your laptop or iPad? Does it make the iPhone glitchy in any way? Does it require a respring before or after use? I've searched and most of the info I read is about problems with the cracked version. I would like to purchase it now since it is through Cydia Store without Rock. I have an iPhone 4 jailbroken on 4.0.1. I would love to here your thoughts on the product from those that bought it. Thanks in advance!
