PC6700 replacement options?

Hi. 1st post.

I had a PC6700 stolen and need a replacement. I want a phone that lets me tether a laptop without additional charges for a few minutes a few times a month.

I heard someone say there is a new phone browser that uses the phone display as a window over regular web pages. I think you scroll/drag the window around to see the parts you need. That sounds very useful.

If the 6700 can't use that browser, can anyone recommend a phone that can use that browser and also tether a laptop?

TIA.
