What is the difference between the two? I've never heard of the E15a.

The main difference is in the UMTS bands

• E15a have UMTS/HSPA 850/1900/2100
• E15i have UMTS/HSPA 900/2100

And all Firmware work in boot devices, but the bands are differents and don't work, I think drivers, but don't know how to correct it.

Well, I imagine there will be a difference in firmware then? Are there any special 2.1 firmwares for your phone yet?

To E15a don't know if exist any 2.1 firmware and don't have a customizations code for this model, I only have 2 codes, the original in my phone 1245-1217 and the used to flash 1.6 and going back to 3G support 1236-9457, these codes don't have upgrade yet.

If you know any customizaton code for this model, i can try to flash or update via PC Companion.

Thanks
