    Default Increasing iPhone SMS Capacity

    Hi, I did a search and came up fruitless on this. So, I'm wondering, is there a way to increase the SMS capacity of the iPhone? If so, how? Thanks.

    Thought it was 100 SMS? You can't change this limit easily since it's hard coded limit in the SMS.app.

    Can you please tell me where is that hard coded limit ? I tried checking the SMS.app and only found it's returned from an imported function, not in the SMS.app itself, here's what I found:

    Code:
    __text:0000FA10  STR     R0, [R5]
    __text:0000FA14  BL      _objc_msgSend   ; controller = [[[SMSUIController] alloc] init];
    __text:0000FA18  BL      _CTSMSMessageGetDatabaseCapacity ; smsSpaceCapacity
    __text:0000FA1C  MOV     R4, R0
    __text:0000FA20  BL      _CTSMSMessageGetCount ; smsSpaceUsed
    __text:0000FA24  RSB     R3, R0, R4      ; smsSpaceLeft = smsSpaceCapacity - smsSpaceUsed;
    __text:0000FA28  CMP     R3, #0x32
    __text:0000FA2C  BGT     csc_return      ; if (smsSpaceLeft > 50)
    __text:0000FA2C                          ;    return;
    __text:0000FA2C                          ; else
    __text:0000FA2C                          ;    // display 'near full' warning
    __text:0000FA30  LDR     R1, =p_performSelector_withObject_afterDelay_
    __text:0000FA34  LDR     R2, =p__displaySMSDatabaseNearFullWarning_
    Thanks.

    well thats saying that if you have 50 sms messages left it will display a near full warning (pretty self explantory) but maybe if you change the > greaterthan to say 100 it might make a difference but I'm not sure and could be wrong. worth a try maybe? won't do any harm..

    bump
    So has anyone figured out how to replace or overwrite the CoreTelephone functions. I assume if we had a way to replace it, it would just return a simple int

    if you change the code to say smsSpaceLeft = smsSpaceCapacity then you're good to go right ?

    From my little bit of computer programming knowledge that little bit of code you found there is purely just to show the warning. Changing it would not change the limit. Rather it would just change when the warning comes up. You would have to find where it starts deleting messages in the code.

    If you do that, you will forever get the "near full" warning, I guess since smsSpaceCapacity is always > 50 I supposed.

    By the way, how do I view the codes?
