old cooked Opera Mini

[voipster]

The current PPC_kitchen_OEM.rar has a slightly older Opera Mini 4. It doesn't have the auto-complete URL feature which I like (in v4.1).

I know I can install the new version, but here's my question. Isn't the "cooked" version in the ROM read-only (can't write)?

If so, can I even upgrade it or do I have to have have 2 versions side-by-side? One in ROM and one in Main Memory - thus taking up my precious Main Memory.

I'm sure I can read the tutorials on "baking" my own ROM, and add the lastest Opera Mini, but I'd still like to know if the "baked" Opera Mini files can be overwritten if I download the latest version.

I think the ROM is read-only, but I could be wrong.
