That's tantamount to saying "I jail-broke my iPhone quickly, so I could use one of the many apps on Cydia to tether my laptop via WiFi" ... except you don't need an app for that because tethering is built into iOS.

It's built into Froyo (Android 2.2) as well.

- every couple of days, you do need to reboot the phone

Don't know if that's a phone-specific issue. Haven't had to reboot my Nexus One except for the Froyo update and instaling third-party ROMs.

- no cellular data while you are in a call

Limitation of the Verizon network. If the iPhone goes to Verizon it too will have that restriction.

I've found I do have to reboot my MotoDroid occasionally. Usually the guilty party is GPS - it absolutely refuses to give fine location unless I reboot the phone.

I've also had issues with airplane mode totally ruining my 3G until I reboot. (I now avoid airplane mode.)

By that time, Verizon may support 4G LTE, at least in major metropolitan areas, which does support simultaneous voice/data usage.
