Having a bit of an issue or maybe I just don't understand something. I'm using Mycelium beta 0.8.5 and it shows my regular balance 2.08+ but my spendable = 0 
The incoming btc shows in my transaction history on 2 deposits. One with 264 Confirmations and one with 104 confirmations. Do I need to wait for a specific number of conf before these become spendable or am I doing something wrong?

I think that you have imported a bitcoin address (without a key) which is a read-only wallet.
In this case the wallet displays the balance of the address on the main view (the sum of the balances of all your addresses).
When it comes to spending it only shows the spendable amount in your wallet, (the sum of the balances of all your private keys).
Let me know whether that was helpful.
