The "a" version supports the HSPA 850 signal type required by certain networks; that’s all.

I just bougth a LT18a and when I was upgrade to ICS also change the model to LT18i. Is there any way to change again the model? I'm from Argentina and here the 3g dosn't work with LT18i bands.

Thanks!

The upgrade was official, with PC Companion.

PCC or SUS wouldn't change the name of your phone

the reason the 3G doesn't work it's not because of the name, it's not software but hardware, you can flash the LT18i firmware to the LT18a, the name will say LT18a bu the 3G frequencies are still LT18i
