Best IOS wallet?

Sorry to ask this on the pool thread, but since it relates to miner wallets I figured you folks would be the best source of information. 

 I am using Mycelium and I like it a lot. But I really need one feature it doesn't have: the ability to set a custom minor fee level. The low priority setting is even too high.    I think it is running about 08 mBTC per byte. Even transactions in the .004 in mBTC area are confirming within a reasonable amount of time. When all I am trying to sweep a miner wallet and I don't care that it takes a day instead of 4 hours, even this low priority level too high.

Any ideas?
