you know this is a string.
|
|
it's a long string.
|
|
it's supposed to be longer than the max message length
|
|
which is 4096 bytes,
|
|
it used to be 512 bytes, but I increased that for the UnifiedPush support
|
|
the 512 bytes was a little short, some people said
|
|
but it kinda makes sense when you look at what it looks like one a phone
|
|
heck this wasn't even half of it so far.
|
|
so i'm gonna fill the rest of this with AAAAAAAAAAAAAAAAAAAAAAAAAAA
|
|
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
