Hi noob here. whats the difference of the customization number from SI number? Coz I was wondering since my Z1 is carrier branded from Smart here in the Philippines, 1277-9538 is the cust number while in the box of the phone the SI number is 1277-9021. Is that perfectly normal or should they be the same? clarification would be greatly appreciated. thank you

yes. It's perfectly normal.

Sales item number should be different from customization number.

For example. Purple or white version (from the same provider) will have the same customization number but different sales item number.

HTH.

Great post, thank you. So what is the difference between CE1, CE3, CE4 and so on? I am just curious.

Default Updating z1 c6903

HI I have a Z1 C6903 on Vodafone uk and there is no update yet to 4,4,4 in UK only on 3 UK. I have the phone unlocked and my sim is a three uk sim. How can I make my phone update to the new three uk 108 firmware when its a vodafone. I changed the customer number in Build prop and also changed the build and it has now come up as there is a three uk update on pc companion , so wondered if ok to upgrade will I loose my sim unlock and need to unlock it again for three uk. I got the mobile already unlocked.

No. You will not lose your sim unlock.

Hi!
1280 might be a prefix for Xperia E1.
