Apple has released its latest iOS 7 update, iOS 7.0.5;
❝ Corrects network provisioning for some iPhone 5s and iPhone 5c models sold in China ❞ — DL1718 
iOS 7.0.5 fixes a few known bugs and also fixes network provisioning for Chinese iPhone 5s and 5c handsets and is a stepping stone for the bigger iOS 7.1 release later this year.
The update covers some international (Asia Pacific/European) iPhone models compatible with China’s network as well as the China-specific models.
iPhone 5s: A1457 (UK/Europe), A1528 (China), A1530 (Asia Pacific)
iPhone 5c: A1507 (UK/Europe), A1526 (China), A1529 (Asia Pacific)
Considering the download weighs in at 1.39GB I would expect more documentation of the changes than Apple currently provide, but this does not appear to be ‘the Apple way’.
