I recently started using an external antenna with great success with my i700. Today, my phone shows "no service" unless the ext ant is connected.

I've had the phone for several months now. It has always had good reception pretty much anywhere I used it except in my office where I wanted to use it as a modem.

I used it as a modem, without the ext ant for 2 weeks and everything was ok. The signal strength was weak in the office, so I added the ext ant. Much improved signal strength. I used the phone in this mode quite a few times over a week. Then, suddenly today, without an ext ant connected, the phone has no service pretty much any where I am??????

Verizon technical support ran me through the troubleshooting process and still no service. I've done the roaming update service (with the ext ant connected) and still no service unless ext ant connected.

Has anyone heard of anything like this?
My phone's pretty much useless as a phone now.....

Thanks,
Marvin
