问题
I had an php app in GAE that i made. At the point only usa was available. (no selection at all)
now i have other app for the same sql-data in eu datacenter. I want to join the 2 apps in eu and using the same cloud-sql instance. Didn't found a way to move app from USA to EU so i deleted the app. 2 weeks have passed and i cannot create new app in eu region with the same id (same address) wtf? I need the same address that was with the old app! I don't mind that the end part of the url is .appspot.com i won't be using my own domain at this point.

You can't re-use the same app ID. Ever. From section 2c in https://cloud.google.com/appengine/docs/python/gettingstartedpython27/uploading:
Also discussed here: How can I reuse an application id on Google App Engine?.
You also can't change an application from US to EU after app registration, see highlighted note right under the above-mentioned 2c paragraph:
So you can only:
- get a new app ID (in EU zone)
- update the old app code with the new app ID (where applicable) and deploy it as the new app code
- access the new app at new_app_id.appspot.com (from the EU location)
