iis app slow loading on first and second request

I'm encountering this weird problem with one IIS Website / app:

The problem is that when i open a web browser on certain devices and access to the app, the FIRST and SECOND requests are EXTREMELY SLOW. It takes up to 30 seconds each to load.

After that everything runs smoothly.

This happens only after opening the web browser on CERTAIN devices. I'll name the devices that the problem persist on and the ones that doesn't.

Devices with the problem: Galaxy S 1 (cyanogen Mod 10) Iphone 4S (stock) ViewSonic VSD220 (runs android ICS) Toshiba Laptop (win vista, i dont have the specs in hand)

Devices not showing the problem: 4 PC running win xp Dell laptop (win 7, i dont have the specs in hand either)

The only common factor I've found is that the problem persist only with this APP on mobile devices. In the laptop scenario i tried with both network cards (wired and wireless) and the results are the same.

I already tried with 2 different IIS servers and different versions (5.1 and 6.0). In different machines... Creating a new the application pool on the 6.0 IIS server... the APP pool recycle timer...

Also this is the only APP i have using .net framework 4.0

any suggestion or help would be really appreciated.

Based on our troubleshooting above, it's determined that some of the app's devices only have LAN connectivity and thus could not access external resources that were referenced in the app.
