I upgraded my device on purpose
我為了某些目的決定要升級自己的機子

I upgraded my device by accident
發生了一些意外所以我升級了

My girlfriend/cat/toaster/etc upgraded my device for me
我的女朋友/貓咪/吐司機(反正就是一切荒謬的因素)幫我升級了

My device came with 3.1.3
拿到機子的時候就是3.1.3版

When I took it to get fixed, it came back with 3.1.3
送修之後回來的是3.1.3版的機器

It was immaculately upgraded
"因為這是一次完美的更新"
意思應該是說3.13你認為很棒才更新的...

I wanted to continue to be able to play online
為了使用可以Online的軟體所以升級(大概某些軟體限定要在3.1.3OS才能用吧)[/QUOTE]
