I want to upgrade my cellphone this month. I've been using the Nokia 5800 for the past 1.5 years. Now, I'm looking to buy an android. The only phones in my budget (23000 INR or 514 USD) the Nexus S, Desire S and the Galaxy S. I'm leaving out the Galaxy S because its not going to get any more android updates. I'm worried about the same thing with the Desire S so I'm kinda leaning towards the Nexus S. Also the dev support for the nexus is great. And I'll be off to study computer science engineering pretty soon, so i'm sure i'll find someone knowledgeable to show me how to flash roms and rooting and stuff. But I'm also worried about the all plastic build of the Nexus S. Please, could someone help solve my dilemma?
