You have to drill a bit deeper as mobile phones aren't an application so it's impossible to determine whether they need layer 4 stability on top of layer 3 mobility.

Actually, it isn't even clear to me that the solutions for hand-off from 3GPP to 802.11 would involve L3 mobility. The hand-off could occur between the lower layers of 3GPP and the lower layers of 802.11, requiring no IP address changes at L3.
