One man's meat is ...!!! I had a very good experience, like you had for your
SE, with the Nokia service guys at Gandhi Bazar: N70 display kaput, repaired in 1 day.
BUT, for my daughter's 2150 it took 10 days, with constant follow-up and dressing-downs, at the Infantry Road (HCL) center. Ditto for a 3650 at the Hosur Road center (again HCL) - where I had gone despite parking problems and all - since I thought the Infantry Road guys were nincompoops.
Funnily, the more feature-packed a phone is, the more the likelihood of failure. You should see the number of Communicators and other high end ones that come for repair! And I have had Alcatel, Siemens and Motorola sets which had never failed for years despite much misuse and lack of care.
