how many times did you able to change your cellphone?  

You would have to check with your cellular provider but I believe the norm is every 2 years. That's if you want a free or discounted phone. Again it depends on your cellular contract. My provider is AT&T and I know they will allow you to change your phone after 1 year but you have to sign a new two year contract. Now AT&T also provides the ability to buy cell phone at full price but without having to sign a contract. If your not able to get a new cell phone without pay more then you want for a new cell phone or signing a new contract you may also want to check out eBay. Sometimes you can find a decent deal on eBay. If you use that route make sure you purchse either a "unlocked" cell phone or one that can be used with your provider.

Woah that's a lot...to me at least.
Anyways so far since i had 2 my first one was like a crappy one and now i have an LG dare. I think taht will last me for a couple of years or so.... Anyways have fun with your cell phones

I think i change my cellphone 5 or 6 times. It wanst that broken or something, i just want to change the unit with a much better model.

I only change my cellphone when its really needed, I guess having numbers of cellphone is not important, its just a way of wasting money.

My first phone was an Ericsson with large and wide body and a very long antenna. It was a gift from my mom when i made it to the pinning ceremony in Psychology. The battery of my phone has run out then later, dad gave me a Nokia 3310. After few months, i sold it to a friend so i can buy a Nokia 5510. I wasn't satisfied so i gave it to my sister then bought myself a Nokia 6600. I dropped it and it fell hard on the floor so again i sold it and bought a Nokia 6680. This is the phone i am using up to now. I'm quite satisfied with it eventhough it's getting old. I got everything i need on this phone. Aside from my Nokia 6680, i still have a Nokia 8210 which i sold to a merchant so i can buy a brand new Nokia 1200. So i'm using two phones right now for two major networks.

Got my first cp (nokia 3315) when i was in college. It was my uncle's gift for me. Memorable indeed but sad to say it was no longer in my care. Had my new now... Im not fond of collecting more phones. I prefer different gadgets as much as it is usable by time.
