On the heels of Tuesday's Samsung Focus 1.4 update comes some more device-specific updates for the HTC Mozart, LG Optimus 7 and Samsung Omnia 7.  The updates are meant to address some significant features, such as battery life, touchscreen response and call clarity.  Because they have been tailor-made for certain models, we do not expect that every phone will receive one.  However, this is not an exhaustive list, so there may be some more lined up.

Have any of you updated, and if so, noticed any improvements?  Are there any devices not listed that you have been prompted to update?
