just a little short temper right now,
please, educate yourself about the way of the mod scene. this rom bases on cm10. cm10 is a new project and things pass that are not really stable. cm10 has not even alpha stage, there are no nightly builds. so as long as its in that stage it will be rough. the basic aosp features though will (should) all work. phone, wifi, bluetooth, nfc, beam, gps, etc. some of the extras that come with cm can be botched, some things can be dinky. some features can be hellish even, like the theming engine which is a MESS. but do not clutter the thread with this stuff.
second thing, gapps. there is no official gaaps package. what you downloaded from goo is a loosely thrown together hacked package. the dev who made it warns you that it can get you troubles. so if gmail crashes, what do you do? you come here and tell me? nope. you go and delete it and get the old (but official) version from play market. just think, would i be so careless to release a rom that would make gmail crash? for most people the gapps are working, who knows what causes for some, but get it from market and fine.
third, apps are botched in tabUI. big deal, switch them to phoneUI. thats the true beauty of it. in tablet mode as it existed before PA these apps would be gone for good. but why they are crashing or displaying weird? this can have many reasons, maybe the screen is too small, just take photoshop or any windows app and make the window really small, you notice something? things overlap or wont fit. another reason could be its using weird percentual or pixel-fixed layout. another reason could be layouts are left unfinished. google for instance did not finish the tabUI for the dialer and many other apps. but since nexus7 runs JB in phoneUI they just left it like this coz no ones ever gonna notice, or so they thought. whatever happens, switch apps like these to phoneUI and gone are your troubles.
fifth, your phone reboots, crashes, is slow, has no wifi, deepsleeps, etc. consider this stuff to be user fault. this is still clean aosp plus a couple of cyanogenbuttons and toggles and spiced up with hybrid magic. but that wont cause anything like what youre experiencing. you probably didnt fullwipe initially, maybe you used a weird kernel, maybe you ticked "set on boot" in your kernelapp and overclockings jerking with your phone. whatever it is, help me, the developer, by taking at least 15 minutes to find the cause. revert, fullwipe, revert hybrid settings, try this, try that, go back to stock kernel, separate the issue, come up with a solution. i just cant be your nanny for essential things.
in the end, let me tell you that if you have a clean install - you wont get reboots, your phone will be blazing fast, you will have wifi and dataconnection, hybrid will work like a charm. its not wishful thinking, im using the rom by myself - and would not use it if it were otherwise. alright?
