How often do you change your mobile phone handset?

If you bought a mobile handset this Jan 2011, how long would you use it? After how many months or years do you have a plan to get a new handset?

 

I don't like changing phones frequently. I buy such mobiles which will have all the features equipped and can be used in future too.
I keep one mobile for atleast 2 years. I was using Nokia 6600 from 2005 to mid 2009 and from then using N95 8GB.
And planning to buy Iphone later this year.

 

I keep my handsets active until it dies out
Right now I'm using a Sony Ericsson K508i, Nokia 5300 XpressMusic and a Nokia N95

 

i changed it only two times .. Now this N97 will be with me for a good while of time..

 

I changed two phones with in 10 years.

 

I changed it every year.

G!

 

Its depend on usage and requirements, for eg: Lots of peoples purchase a Android phone for checking android functions,etc..

If I will buy mobile in 2011 then I will try to buy new mobile after 4 years(at lest 4 - 5 yrs.)

 

I also got my first mobile in 1995, it was a Motorola d160

 

in 1995?? i never knew anything about mobile at that time

 

I usually change it after 2 years , got my last phone an year back so will change it next year.

 

Every 2 years when my contract is going to be renewed

 

While my first cell phone lasted for four years, the second one bid farewell in 3 years. The third one became less smarter in another 6 months and now I am with my fourth cell phone which is 6 months old. Looking for another feature rich phone and soon will get one.

 

I change my phone every 2 years (because of the discount)
I found that if you call the place (I use verizon) you will almost always get a better deal than buying online, because they can always give 'special' deals or promotions that you may not know about

 

I changed my handset every two years, which was the common service life of my phones

I dont change my mobile sets quite often I use it atleast for 3-4 years and when it goes bad i buy new one

 

I change my phone when ever my contract allows me to

 

I change it whenever Robbers lets me upgrade usually every 2 years.

 

I think 1 month once.. or 2month!
