I just moved from the 8703e to the 8130 on VZW. It is a great device. I am adjusting back to the Suretype.
Before I switched however I did put another vendors upgraded OS on my 8703 and it made some really cool upgrades which included the ability to use the Media Manager with the 8703. I was able to drop pictures and ringers on it from my PC. That allowed me to have picture caller ID etc. It had the Today theme even. Wild wild stuff. With the limited RAM on the device you can't do movies and music but I use mine for work so that didn't matter. If you switch to the Pearl you won't regret it but try to upgrade the OS on your 8703 before you do to see if it gets you through.
You know as soon as you switch Verizon will have the Curve out a month later
