I’m want to know,who’s use iPhone3G or 2G, that is install jailbrake to test game from unity iPhone? and what do you setting Unity iPhone when you export and build it in XCode.

Thanks

jailbreaking has no impact on the xcode settings, they are just “not that restrictive” iphone os installations where your apps commonly run worse / crash due to the lifted restriction of no background apps

Thanks first,dreamora.

My customer use iPhone3G/2G and iPod Touch 2G with Jailbrake,they buy my game from iTunes store but it’s crash when they touch start game. but no problem when use iPhone3GS or iPod Touch 3G with/with out Jailbrake.How I suggest them or What can I do for fix this crash.

ps. I have no testing machine that jailbrakeing and my game use memory 2-5 MB only.

Thanks

you can not do anything.
Due to their OS breaking the rules of the iphone, they are running on too little ram.
They need to get their ram cleaned up correctly by fully restarting it and don’t run background applications if they want to play your games.

3gs don’t have this problem because they have another 128mb of ram to compensate for the jailbreak userfailures.

So either the users fixes his errors or its his problem (as far as I’m aware he isn’t even entitled to a refund in this case as he broke the app store contract)

Thank you so much. It’s very helpful. You know it’s make me sleeping in nightmare for many night. Some customer post my rating in iTunes store to 1 star, because they cannot to play my game in this case :cry:

That they can not play it must not needfully be a jailbroken users.

Many devs make the serious error of having “clean” test devices which commonly have far more memory remaining than fully loaded ones.

You should check your app with the memory instruments. If you go above 35MB you are likely killing pre 3GS devices and should correspondingly either get the ram usage under control or set your app to be sold to 3GS only

Thank you again, I must be checking it again and strong optimize for next update . :slight_smile:

Crashes due to jailbreaking is not inside your responsibilities.

What you should do is to add a warning inside your app description. Something like : “Warning, several tests have shown some crash situations when this game is run under modified OS, for untracable reasons.
We do not take any responsibility of malfunction under modified OS.”

Then it’s up to users to decide. As Dreamora said, there are so many external factors for an app not to start under Jailbroken device that finally, it would be a waste of time to search for solving every JB crash.

Older systems like 3G iphone / 2G iPod have a very limited amount of memory. If Jailbroken OS allow several apps to occupy that memory, wanting to solve crashing problem would mean not to exceed an overall allocation of maybe 6 to 8 MB.
Nowadays, if you want to make a competitive game, this is just impossible.

Thank you very much. I spend many time fix it. I thinks maybe a time to stop is coming. Can I get your sentence “Warning, several tests have shown some crash situations when this game is run under modified OS, for untracable reasons.
We do not take any responsibility of malfunction under modified OS.” to edit in my game information. because my English is poor :lol:

You are absolutely free to use this sentence, of course :slight_smile:

I made a typo error : it’s spelled “untraceable”, not “untracable”.

Thank you sir :smile:

you wouldn’t believe some of the things people do to their machines expecting them to run games well… they run skype in the background… have winterboard and sbssettings… etc… I ssh’d into a friend of mines machine and his phone was idling at 50% cpu use.

ignore them, not your problem. I have a hard enough time balancing cpu/gpu budget without taking idiots into consideration…

not that jailbreaking is all bad, I’ve done it to play with the unofficial sdk, and before 3.0 it had video capture and cut and paste… but to do so and then expect the same battery life and performance is just asking for trouble…

Thanks for your opinion. I’m agree with you. I work hard with clean coding but when it had problem, I’m being mad.LOL
