Worked well enough in the trial period,so I bought it as I was going away on a trip and knew I'd want to use it. Been tethering with my iPad (on beta 4.2 so honestly this could have a lot to do with it), but had several irritating problems. One is that it wont connect reliably with wep. I rebooted the iPad and it did connect, but lost the connection shortly thereafter. Also, it has lost connectivity several times after about 20 minutes. I have to stop mywi and restart it. Lastly, even without wep the iPad does not reconnect reliably. After starting mywi I always have to manually connect the iPad. Are these issues normal? Honestly, if they are, I'm glad I bought a 3G version iPad because in the future I'll probably just pay for the Internet connection directly - this is a bit of a pain. Good news is that battery is better than expected - seems to be using about 10% per hour on the phone, which is completely reasonable, and frankly considerably better than mifi devices.
