[Q] LT15a Running LT15i - ICS 4.0.4 Update

---

I have my Xperia Arc (LT15a Rogers) running the LT15i Generic World (4.0.2.A.0.62) ROM, and with the imminent update to ICS 4.0.4 soon, I'm wondering how the update will work for my device.

Will running a different ROM from what it originally came with (Rogers-branded LT15a) affect my updating process? Or is it all dependent on the SI number under the battery? Also, is the update supposed to be OTA, or available through SEUS or something?

Can someone please help me? =S

Your phone only checks for updates for the version currently running on your phone. That aside, why would you wait for Rogers to release it when it likely won't be directly root-able (and since I assume you have a carrier-branded device, you can't unlock your bootloader except through the paid method to root) and won't be out for weeks.

The LT15a generic America ROM was released a few days ago, bloat-free and root-able. Use that.

(On a separate note, OTA is only for incremental updates. i.e. 2.x.x to 2.x.y, 2.k.m to 2.k.n, 4.0.w to 4.0.v, etc. Major updates between versions must be done through PC Companion.)
