Other phones that have the same internet sharing capabilities as the HTC Touch P

Immediate assistance required: Phone with internet sharing capabilities.

So my brother's girlfriend is looking for a new phone from Sprint. She is allowed an upgrade and we're taking advantage of these discounts from the upgrade discount from Sprint. We're not looking to switch carriers.

We need to know which of these phones from the list below have internet sharing capabilities like the HTC Touch Pro. So for example, right now I am typing this post using my Touch Pro as my internet connection. Which of these phones can do that? Thank you!

(This is not just for her but also for me if I ever want to change my phone from the Touch Pro to something else. I appreciate your quick response!)

The LG Lotus and LG Rumor both have internet browsers built in

Teathering could be a different story (hooking your phone up as your internet connection)

The Lotus does have teathering capabilites, but you'll need to get a PAM (Phone as a Modem) plan add-on
