Xperia T update: tethering problem not fixed

[CCWH68]

Hi,

On my Xperia T with ICS it was impossible to use the tethering (no internet).

Unfortunately with Jelly Bean update this problem was not fixed.

Please Sony Mobile fix this bug.

My cellular company: SFR (France).

Some operators may not allow tethering. Have you checked with your operator so that they and your subscription supports tethering?

Tethering (modem) is allowed.

SFR has a lots of problem with Xperia devices running ICS and higher.

Same smartphone's with GB work great. After upgrade impossible to use tethering (same APN in settings)

ICS update (and JB) have introduced a bug.

On my Xperia T (ICS in the beginning), tethering has never worked !

My old Xperia x8 (eclair) work well with the same subscription and same APN in settings

I have contacted Sony Mobile support who confirmed the bug for ICS.
They say that a fix will be introduced with the upgrade to JB for my Xperia T.

But, now i have JB and i have the same problem.

There is a very big theat about this problem on Sony Mobile Forum
