Version U8650V100R001C151B863sp02 is the newer version of the two. It is the Indian Version of the software provided with Android 2.3.5. It contains a lot of extra software advantages and also includes Cloud Services.
It would be better to update to this as it brings a number of improvements and fixes compared to your old software. I updated from that version and in my opinion it is much better to update to 2.3.5 provided by Huawei India.
Your information is appreciated. I've now upgraded two of the family Huawei Sonic's without any problem. The upgrade certainly is worthwhile even if only using mobile phone voice calls (which seems most +40 year olds do !!!). Thanks james - and to the other contributors who have provided valuable information re the upgrade. Currently I'm using Australian (Sydney) purchased TravelSIM for trip to Europe. This is probably not the forum to discuss ISP/SIM's but being a new "new chum" from the DOS era, some one may be able to direct me to the right place. Thanks in advance.
