Blackberry curve or nokia astound?!?

i have tmobile and i really want a new phone but i cant decide between the blackberry curve or the nokia astound. they both cost the same so thats not really a problem. the nokia has the ovi app store and the camera in the front but its only compatible with other nokia astounds, maning i couldnt use skype or oovoo with anyone and i could only video chat with them if they have the same phone as me. its all touch screen and i like that because im a really big texter so i can just turn it to the side to type anything, its just a pretty long phone. on the other hand, i hear blackberrys are REALLY good and they are like an iphone, or just as good as one. i love how it looks and the shape of it but im worried hat the keyboard would be a problem for texting because the keys look small. im usually on social networks alot so im not sure which would be better. if you've ever had these phones please tell me what you would reccomend and why, im having a hard time trying to decide!!
