I am planning to buy Xperia X10 from USA.

It has two models: x10i and x10a supporting the following frequencies:

X10I......... GSM850, GSM900, GSM1800, GSM1900, UMTS900, UMTS1700, UMTS2100 .................... HSDPA 7.2 Mbit

X10A........ GSM850, GSM900, GSM1800, GSM1900, UMTS800, UMTS850, UMTS1900, UMTS2100 ...... HSDPA 10.2 Mbit

Which one would work in India?
