I dont really know what to suggest , buy a phone at good price with good resale value so after you are finished playing around with it you can hopefully sell it for the same price or even more.
HD2 would be a great choice if not that then go for Desire. Do you have an android phone right now? I know a trick to get free apps.
I tried to use tapatalk but it wont run pakwheels , will fix that when i get time.
qwerty keyboards are worthless on touchscreen phones.
If you can manage to get a Htc Surround , that would be a great option but i dont know about its resale.
