China ROM - compatibality issues with certain apps

[sasukewa]

I have a few questions for people who are on the China ROM.

I cannot install the app list below:
1. Ebay
2. Facebook
3. Gumtree
4. Paypal
and a few other apps.

I transfer the app apk each time from my other phone with Google Play Store. I just want to know what other apps people cannot install and how they got around it. My reason for running China ROM is to see if the battery life is actually any better. Thanks.
