This bug is a regression from Bug 735581. the argument for EF path should be pathid, instead of path.
Find out it's the problem of Bug 720638. Android emulator doesn't check EF_Path argument so I get always get the number. This also explains why I cannot get phone number on my device. reopen Bug 720638.
Please don't reopen bugs for follow-up fixes. Follow-up bugs are the correct way to deal with those.
Created attachment 607843 [details] [diff] [review] fix typo in iccIO Fix typo in iccIO. It seems Ril didn't check EF Path at all so I didn't spot this typo in the first place(Bug 728638), sorry for my mistake.
