No internet connectivity when connected to BTOpenz...

Question

Having moved to BT and paid the extra £10 a month over O2, to allow my mobile device to access BTOpenzone and BTFON, I am finding it extremely difficult to get my money's worth.
The BTFon app has only twice managed to automatically connect to and gain internet access. Another couple of times, when mucking about with Safari (it's an iPod Touch) I've managed to stumble across the BTOpenzone landing page and manually log on.
But most of the time, while the BTOpenzone and BTFON networks can be joined in Settings (and shows a tick) then Safari says that I am not connected to the INternet, and BTFon will come up with either "this wifi hotspot is temporarily unavailable" or "not connected to the internet".
This is now even the case when I am at home and connected to my on HH3, the BTFON and BTOpenzone connections will just not allow internet access or come up with the Openzone landing page.
Now in the case of my own HH3, checking the IP address  I note that it starts with 10 as in 10.227.71.139, when connected to BTFon or Openzone (it's 192 when directly connected to the SSID) and the router is 10.227.71.137. There are just the two DNS entries 192.168.22.22 and 192.168.22.23.
The sticky above says that the IP shouldn't start with 10, and that the HH3 needs reset.
Now, the HH3 is still just a few weeks old, and I am not inclined to reset it as I can access the normal SSID network anyway. But it occurs to me that if it requires a reset so soon, then most folks' HHs will also be in this position. It also means not only that no-one can use my own BTFON and explains why most others are unavailable to me when I am roaming.
If that is the case I am wondering why I bothered paying the extra to move to BT and has huge implications for the functionality of BTFON in general.
If the above is all correct then I think that BT should sort out the firmware and roll out to all HHs automatically that are opted in to (or not opted out of)  BTFON. the firmware should identify what it is that makes the homehub issue IP adresses starting 10 instead of 192, and fix that without a reboot. 
This will then allow devices to connect, without requiring users to try and find the one HH in the area that does not require rebooting.
Of course I will be delighted to be proven wrong and that there is some simple solution to the above!

Although I'm not an i'anything' user, did you do this when you first used the app?
taken from http://itunes.apple.com/gb/app/btfon-wi-fi/id384404559?mt=8
Here's how to use it for the first time:
1. Download and open the app and then click on ‘I’m a BT broadband customer’
2. Type in your @btinternet.com email address and password then read and accept the T’s and C’s. This will automatically opt you in to BT Fon
3. When you’re in a BT Fon or BT Openzone hotspot for the first time, click on Settings on your iPhone home screen, then Wi-Fi and select BT Fon or BT Openzone (you won’t need to do this again but must do this to use the app for the first time)
4. Open the BT Fon Wi-Fi app and you will automatically be logged in
5. If you want to connect to your Home Hub rather than BT Fon, you simply click settings on your iPhone menu screen, select Wi-Fi, and then choose your Home Hub
