My desire for the phone arose due to its advertising by Nokia... there were 8250 ads displayed everywhere!
My decision to buy this came back in March 2001, & I checked out BidorBuy India & found Kishore Mulani (98200 23366) who gave me an unconditional year long guarantee with a bill on the phone. The price paid was Rs. 19200/- all inclusive. I had explained my needs to him & ensured that the phone would be a good buy with at least 3 hours of talk time between charges - something I needed as Im a heavy user & hate low battery warnings. (I smashed my last phone, a Nokia 8810 - theres a review for that as well on MouthShut - due to its lousy battery performance & overall shittiness)
I had a great time with the phone... my friends all wanted one & the size was fantastic! I would often lose the phone in my trouser pockets. If they stuck on a loop, you could use this baby as a keychain!
However, within two months, I had to replace the battery, as it was dying in front of my eyes... With Kishores advice I went in for the J-2000 which has lasted me with my heavy use (3+ hrs talk per day, full charge overnight, phone always on) till date, over 16 months.
This model is basically an ergonomic & aesthetic upgrade over the 6250 - the buttons are designed to have an easy feel for non-visual use. The colour & intensity of the blue display light vary from phone to phone - I use mine like a torch in situations.
All in all, I would recommend this for the size, reliability & features. Its memory could be upgraded to the new series (6210 / 7110) to make it absolutely perfect.
