I waited for the update to be available before buying, but the software is not usable for me. Following is the review I posted on the App Catalog:
Even after this upgrade, this app is unusable on my Pre Plus running WebOS 1.4. It takes forever to load contact lists, and my Pre is super slow during the load. Once the list is loaded, I can't scroll it. Too bad for me since I have more than eight contacts!
I used IM+ and IM+ for Skype on my Palm Treo, and then Centro, and became a loyal fan of Shape Services, and so I still believe they will eventually release a quality product for WebOS. However, this experience shows me I can no longer trust Shape's commitment to quality. I'll do a lot more research in advance before paying money for a Shape Services product--just as for any company I don't know I can trust to release only quality products.
