- Firmware версии 3.62 В 9210i не засунуть. Вернее, чисто теоретически на программаторе можно, а практически с помощью Box'ов - нет.
У тебя 9210 просто, без i.- Отличия 3.62 и 4.13 прошивок друг от друга:

- Для меня главное во всех этих прошивках - возможность подольше не перезагружать телефон. 3.54 держалась пару дней, 6.00 - живет недельку без проблем.
- Прошить трубу на данный момент можно двумя боксами: великолепный Гриффин
(Griffin BOX from Griffin Team), который стоит ~$450 и Prodigy BOX ~$150. Ими обоими торгуют на радиорынках. Про первопрестольную не знаю 
а в Питере - Юнона. Остальные DCT4-Box'ы стопроцентно НЕ прошивают 9210i, а 9210 - нужно экспериментировать. Хотя сейчас я не успеваю отслеживать инфу по прошивке, так что может чего и поменялось на рынке. (2All: Если заметите несоответствие, просьба не пинать ногами, а поправить )PS Мое мнение: есть возможность - обязательно перепрошей. Содержимое памяти телефона не слетит при перепрошивке, меняется только флешка. Это справедливо для Гриффина, другими не шил...
Сервисмены наверняка форматнут телефон. Тебе тоже, скорее всего, придется это сделать. Все-таки разница между 3.62 и 4.13 существенная. Я после перепрошивки с 5.54 на 6.00 даже не форматировал телефон... PPS $30 без гарантии за смену прошивки в сервисцентре - непозволительно дорого.
Ищи флешеров за $10.
