good luck finding a store with a 6700. Mine died about a month ago and it had to be replaced with a 700wx. I thought I would give it a go but to be totally honestly I really want to be back on a 6700. The phone does work better on the 700 but when I am in my car using my BT GPS and I try take a call with my BT headset the phone craps out. I have the update BT software from the 750 but it still has the issues. My 6700 would have been fine using it like that. The 700 does seem a bit faster but all in all I do think the 6700 was a better device esp. after getting AKU3.5 to work.
When my phone died I had them look nation wide for a replacement 6700 and they (at the time) only found one. Getting it to me would take a couple of days so I had to switch since I use it for work. Does anyone know if they will switch it back if a device comes available?
