"good day fellow jailbreakers & unlockers
i hope those of u with 3g/3gs are enjoying their updated unlocked devices, all props to @MuscleNerd & co. for making this possible
, hopefully the iphone 4 on 2.10.04 and 3.10.01 follows within a good time table.
on a very important side note, before anyone starts to complain about battery drainage issues after installing the new ultrasn0w on the 6.15.00 updated BB, the culprit here is not ultrasn0w, it's the hacktivation process (activating the phone by pwnage tool or redsn0w rather than using an official carrier sim to do so) that u mostly did while jailbreaking.
The 4.1 and 4.2.1 ipsws unlike their old ancestors, seem to keep looking for valid push certificates all the time, either thru your wifi, or thru your cellular data network (which u only have after installing ultrasn0w and hence u accuse it) , this can be seen clearly if u have a cellular working data plan for 3g or edge and u watched the settings > general > usage > cellular network data (sent & received are continuously increasing even without using any internet traffics on the phone) , this will also render the phone going hot even in stand by mode and also very rapid battery drainage occurs plus consuming ur data if you were not on an unlimited plan.
so to resolve this, u either:
A) try to activate the phone using the official sim if u have it (even if the sim itself is old and not working) , or borrow it from a friend if it's possible, by any means, try to have an access to one and use it
if A is not feasible, u can install SBsettings from featured cydia packages and turn wifi and data off when u r not using it (shuts down both 3g and edge) , till C is done
C) there is a very nice module being worked on by a trusted jailbreak app dev, namely @sbingner , which ll resolve that issue for those having it, the details of which shouldn't be disclosed until he finishes his awesome work, till then, either use A or B to resolve the issue if it exists for you
sorry for the long post and thanks for your attention "
Με λιγα και συντομα λογια, οι εκδοσεις 4.1 & 4.2.1 εχουν ενα "θεματακι" με τις διαδικασιες hacktivate & unlock που μπορει να οδηγησει το τηλεφωνο μας στο να ειναι 'ζεστο', να καταναλωνει ασκοπα data μεσω 3G κλπ... Ελπιζω να βρεθει η λυση ενω ταυτοχρονα αναρωτιεμαι τι θα συνεβαινε αν καποιος εχει τα SHSH οποτε να χρησιμοποιησει την 4.0.1 (ή 4.0.2) ας πουμε, με την ΒΒ 6.15. Θα δουλεψει αραγε ο συνδιασμος? Παντως αρκετος κοσμος αναφερει οτι η ΒΒ 6.15 σαν σχεδιασμενη για το iPad ασχετα αν προοριζεται για το ιδιο chip, δεν εχει μελετηθει για την ταυτοχρονη εκπομπη/ληψη φωνης με δεδομενα 3G (προφανως γιαυτο και οι λυσεις τυπου, "κλεισε το 3G" κλπ). Εγω προσωπικα ελπιζω να βρεθει καλυτερη λυση εστω και λιγο αργοτερα και ετσι παραμενω 4.1, ΒΒ 5.14.02 και.. ipod!
