PDANet typically offers free upgrades unless there is a new major version or if the phone changes. They let you use the software on both phones on the same account similar to itunes. Finally its totally agreed that they should have been upfront with the charges but then again, they have the best software in the market today and for all the efforts put in, I feel we should support them and make the purchase. Excerpts from their reply: Upgrades are most likely free unless a totally different phone comes out and totally breaks PdaNet. If you check our websites PdaNet has been priced at $34 for other platforms so this is already a discounted offer. Believe it or not our company doesn't profit from this overall (unless apple approves PdaNet in the app store). But it will help us continue development. Feature Request Features: Battery Charging with Tethered. 100% Aventail VPN support. (No Big Requirement at all but there are companies out there that use Aventail instead of the regular Cisco, Notel). 20% Make the phone initiate the adhoc network.
